“Gucci’s brand value gets diluted. Items like this hurt the bottom line, because there’s market substitution,” Director of the Fashion Law Institute at Fordham University Susan Scafidi said. “People trade down or fail to buy the original.”

The Gucci bomber jacket retails for $3,400, while a very similar Forever 21 jacket sells for $27.90

That’s why a shopper at Jersey Gardens told CBS2’s Meg Baker the retailers are not competitors – they attract totally different customers with different sized wallets.

“No, that’s ridiculous. I wouldn’t spend $3,000 when I can get a replica for 22.90,” she said.

“Forever 21 is focused on the stripes and claim that they used blue, red, blue stripes randomly. Gucci would like the court to look at this and say, ‘Oh no, that wasn’t random. You’re copying the entire Gucci product and attempting to convince the consumer to think about Gucci when it’s really just Forever 21,’” Scafidi said.

“At the end of the day, Gucci is top of the line. That’s the original,” another shopper said.

In a statement to CBS News, Forever 21 called Gucci’s claim false and said, “clothes with this same, common stripe design have been sold for many years by many different brands and remain widely available today.”
